6 months
None. A decade is a period of ten years. You would have at least 120 months in one decade. 120 months = 1 decade 6 months = 6 x 1/120 decade = 0.05 decade
December is the 12th month so it would be XII. 6 is VI and 1998 is MCMXCVIII. It would be written: XII VI MCMXCVIII.
Take your original birthday (example: July 7th), and add exatly six (6) months to it (the half birthday of our example would be calculated like this: 1.) August 2.) September 3.) October 4.) November 5.) December 6.) January so the half birthday of July 7th would be January 7th)
....52 weeks in a year, so 325 weeks divided by 52 = 6.25 years..... that would be 6 years and three months (¼ of a year), so it would be either 6 years and 93 days (3 31-day months) OR it would be 6 years and 92 days (2 31-day months + 1 30-day month) OR 6 years and 91 days (1 31-day month and 2 30-day months) OR 6 years and 90 days (3 30-day months).....get the idea? Or for that matter, it might be as little as 6 years and 88 days, if you use February..

December 4 + 3 months = March 6.
